Today my new p5q deluxe arrived to replace my p5n-t which had recently died. What happened was over time it started crashing more and more frequently until it no longer POSTed. There were no beeps what so ever so I presumed the worst, that it died. Anyway after fitting the new motherboard I get the same problem no post whatsoever although everything spins up properly.

DrPepper recently tested the power supply and the GPU in his pc and they worked fine and I cannot think what is wrong. I read a guide here suggesting that no beeps was the sign of a dead mobo. What do you think is wrong and what do you recommend ?

If it's the exactly same problem, then one of the pieces of hardware has died. If it's not PSU,GPU or motherboard then it's possibly memory or HDD (dunno how it could cause that but it's the only other piece of hardware.) And well, just check your CPU to be on the safe side.

It could possibly be your motherboard, but I would try it with a different CPU first. Or maybe, reset the CMOS and/or check the clear CMOS jumper and make sure it isn't set to clear. I think they ship motherboards with that jumper set to clear to conserve the battery, but I could be wrong.

Try disconnecting everything apart from wots needed to get the mobo & gpu powered up. It maybe a cd drive or something. I once had probs with a pc crashing & shutting down turned out to be the LCD clock/CPU temp gauge. Once i unpluged the power to that prob gone !

so far i look over and as Dr pepper said , i believe it to be a DOA. I made a thread about 2 weeks ago asking for help on strange developing problems with my P5NT deluxe . The sound would die at random. The internet would cut at the port and crashes on the bios were not uncommon. This lead me to buy the P5Q. tests on all devices were carried out , they were fine.

will you test all your parts in another pc? maybe some hardware is killing your MB.

I put the pc together and I've never killed any of my own or anyone elses hardware. I tested most of the stuff in his pc except cpu and they all worked fine. I didn't test his cpu because mine didn't work in either of his dead mobo's.
